Measurements of isobaric heat capacity of gaseous R1234yf.
Number: pap. n. 1011
Author(s) : KAGAWA N., MATSUGUCHI A., WATANABE K.
Summary
The specific isobaric heat capacity (cp) in the gas phase was measured for R1234yf (2,3,3,3tetrafluoropropene). Twenty-two measurements for R1234yf were carefully measured at temperatures from 315 K to 353 K and at pressures from 0.5 MPa to 2.2 MPa. The expanded uncertainty (k=2) of the temperature measurements is estimated to be less than 27 mK, and that of the pressure measurements should be less than 9 kPa. The expanded uncertainty for cp is calculated to range from 15 to 35 J·kg-1·K-1. The measurements were compared with two published equations of state.
